Businesses are set to benefit from improved east-west rail services between Manchester Airport and Cleethorpes.
TransPennine Express and Northern Rail are looking at improving Sunday services and enhancing the weekday service.
More train times could be added for Saturdays and in the week.
These new TransPennine Express services are expected to be implemented in December 2017.
Northern Rail is proposing changes to services from May 2018. These include extended train times between Scunthorpe and Sheffield.
North Lincolnshire Council has welcomed the plans.
Councillor Richard Hannigan, cabinet member for safer, greener and cleaner places, said: “TransPennine Express and Northern Rail’s plans offer an improved service for residents, especially on Sundays.
“We are working with the providers to secure even more improvements for railway services in North Lincolnshire.”
